... Up to four unique key sets may be used for these operations. The AT88SC1616C offers the ability to communicate with virtually any smart card reader using the asynchronous protocol (Gemplus patent) defined in ISO 7816-3. ...

... The AT88SC1616C provides an ISO 7816-3 compliant asynchronous answer to reset sequence. When the reset sequence is activated, the device will output the data programmed into the 64-bit answer-to-reset register. An internal pull-up on the RST input pad allows the device to be used in synchronous mode without bonding RST. The AT88SC1616C does not support the synchronous answer-to-reset sequence. ...

... To gain access to the configuration memory, the secure code must first be successfully presented. For the AT88SC1616C device, the secure code is $20 0C E0. After writing and verifying data in the configuration memory, the security fuses must be blown to lock this information in the device.
